Five compounds were isolated from Capsicum annuum by means of various chromatographic techniques (silica gel, Sephadex LH-20, MCI GEL CHP-20P and HPLC), and their structures were determined as luteolin-7-O-[2"-O-(5"-O-sinapoyl)-beta-D-apiofuranosyl]-beta-D-glucopyranoside (1), uridine (2), adenosine (3), 7-hydroxy-6-methoxy cinnamic acid ethyl ester (4) and 7-hydroxy cinnamic acid ethyl ester (5) by extensive spectroscopic analyses (UV, IR, MS, 1D- and 2D-NMR). Among them, compound 1 is a new flavone glycoside named as capsicuoside A, and cmpounds 2-5 are isolated for the first time from the fruits of C. annuum.

PURPOSE: This study was done to evaluate the combination effects of capsicum plaster at the Korean hand acupuncture points K-D2 with prophylactic antiemetic on Postoperative Nausea and Vomiting (PONV). METHODS: An experimental research design (a randomized, a double-blinded, and a placebo-control procedure) was used. The participants were female patients undergoing gynecologic laparoscopy; the control group (n=34) received intravenous prophylactic ramosetron 0.3mg, while the experimental group (n=34) had Korean Hand Therapy additionally. In the experimental group, capsicum plaster was applied at K-D2 of both 2nd and 4th fingers by means of Korean Hand Therapy for a period of 30 minutes before the induction of anesthesia and removed 8 hours after the laparoscopy. RESULTS: The occurrence of nausea, nausea intensity and need for rescue with antiemetic in the experimental group was significantly less than in the control group 2 hours after surgery. CONCLUSION: Results of the study show capsicum plaster at K-D2 is an effective method for reducing PONV in spite of the low occurrence of PONV because of the prophylactic antiemetic medication.
